基于可测度分析的雷达系统误差估计

Radar Systematic Error Estimation Based On the Analysis Observability

建立了多部雷达情况下的系统误差观测模型,分析了系统的可观测度,得出可观测度不一定随观测数据的增多而增强的结论。在此基础上,通过数据筛选的方法,可以获得一个使系统可观测度增大的观测子集,用于误差估计。实验结果表明,使用本文的方法。

In this paper, a systematic error observation model for multiple radars is established, on the basis of which the system observability is analyzed and a conclusion is drawn that measurement accumulation does not always lead to higher observability. According to the conclusion a measurement subset can be produced by means of data selection, which causes higher system observability, to estimate the systematic error. Simulation result shows that the method proposed in this paper can ensure the validity of estimation algorithm.
